Arcom Embedded Linux Technical Manual Developing software for AEL

2 Configure the application:

$ ./configure --prefix=/usr --host=arm-linux

$ make

Again, note the use of the --host option. For more information about this

option, see Common open source build systems and cross compilation

page 38

3 Install for the target:

$ make install-strip DESTDIR=/tmp/trivial-app

Installing on the target

To install the application on the target, follow these steps:

1 Generate the tarball to be installed based on the installed files:

$ cd /tmp/trivial-app

$ tar czvf ../trivial-app.tar.gz *

$ cd ..

For a real application, you may want to remove files that are not required

on the target (such as documentation) from the temporary folder before

you build the tarball.

2 Transfer the installation tarball to the target board using scp (example assumes

that target board’s IP address is 10.2.55.5):

$ scp trivial-app.tar.gz [email protected]:/tmp

If DNS is set, you can use the name of the target board in above command

(example assumes that the name of target board is penguin.example.net)

$ scp trivial-app.tar.gz [email protected]:/tmp

3 Enter the following command on the target board (as root):

# cd /

# tar xzvf /tmp/trivial-app.tar.gz

4 Update the shared library cache:

# ldconfig

5 Run the application:

$ trivial-app

The following message is displayed:

This is a trivial application.

This is a trivial function in a trivial shared library.
